At the DMH household, we swapped out all of our regular incandescent light bulbs with the hot new squiggly compact flourescent lightbulbs.

And the bulbs burn cooler and last longer.

That factoid, and many other money hacks, are available at this week’s Carnival of Money Hacks hosted by Moolanomy. Incidentally, that factoid was provided by GE Lighting in their Compact Fluorescent Light Bulb (CFL) FAQ.
